Question

Is there a way to do an exclusive or in EL? I have two variables. I want to check if only one of them is empty at a time. I understand I can do this manually by doing the following but I wanted to know if there is an EL keyword for it?

<c:if test="${(!empty var1 and empty var2) or (empty var1 and !empty var2}>
    ----Do something here.. 
</c:if>

Answer 1

EL doesn’t have an XOR operator, but since both expressions return boolean already, just compare them by !=.

<c:if test="${empty var1 != empty var2}">
    ----Do something here.. 
</c:if>
